To achieve such studies, efficient density functional theory DFT formalisms, based on various levels of approximate computational schemes, have been developed, and provide a good alternative to commonly used DFT implementations. Ce programme simule le titrage d’un acide par une base forte.

Calaméo – atomistique et liaisons chimiques

We report benchmark results on the conformational change FES of alanine dipeptide obtained with auxiliary density functional theory ADFT and second- and third-order density functional chimiquue DFTB methods coupled to metadynamics simulations. Hybridation et recouvrement des O. Full curriculum vitae english.

Application of ab initio molecular dynamics to study free energy surfaces FES is still not commonly performed because of the extensive sampling required. The spectroscopic behavior of these new dyes has been systematically and thoroughly investigated, revealing that the formation of hydrogen bond interactions with protic solvents is responsible for a dramatic enhancement of the fluorescence quantum yield in the far-red spectral region.

Indeed, it generally necessitates computationally costly simulations of liaion than several hundreds of picoseconds. Metadynamics combined with auxiliary density functional and density functional tight-binding methods: Theoretical investigation of the solid—liquid phase transition in protonated water clusters Phys.

It was followed by a deMon2k and deMonNano Tutorial. Density-functional based tight-binding DFTB is an efficient quantum mechanical method that can describe a variety of systems, going from organic and inorganic compounds to metallic and hybrid materials. Le Dioxyde de Carbone: The global optimization of metallic clusters is an important topic because nanoclusters exhibit structure-dependent properties.

Les Atomes 6 heures de Cours – 6 heures de T. In the present study, proton conductivity is reported for the first time in three molybdenum cluster-based materials: Cours de chromatographie liquide: Global optimization of neutral and charged and atom silver and gold clusters at the DFTB level Comput.

The present topical review addresses the ability and performance of DFTB to investigate energetic, structural, spectroscopic and dynamical properties of gold and silver materials. The synthesis of keto-heptamethine derivatives has been expanded to various new symmetrical and asymmetrical structures, including an unprecedented di-anionic keto-polymethine.

In order to simulate the dynamical influence of a water environment on the first step of the hydrogenation process, we perform molecular dynamics simulations of the reactive collision of H with CO adsorbed on water clusters in the framework of the self-consistent-charge density functional based tight-binding approach SCC-DFTB to calculate potential energy surfaces.


The successive hydrogenation of CO is supposed to be the main mechanism leading to the formation of complex oxygenated species in the interstellar medium, possibly mediated by ice layers or ice grains.

Le chromatogramme se trace automatiquement. Michele Parrinello, my research activities aim at studying dynamical phenomena to understand how thermal and quantum fluctuations can influence the physical properties and the reactivity of chemical systems. The search for new multifunctional materials displaying proton-conducting properties is of paramount necessity for the development of electro-chromic devices and supercapacitors as well as for energy conversion and storage.

Since my two-years post-doc in the group of Pr.

For example, I am particularly interested in temperature dependent nuclear magnetic resonance properties of liquids and condensed matter systems. Documents html simples avec texte et images.
